Question

Does the efficiency of a motor depend on mass?

Answer 1

Practically yes

• Efficiency=Output/input

So

If mass is more output may come less so it affects the efficiency practically

But thepritically it doesn't

Answer 2

Answer:

Yes

Explanation:

Formula of motor efficiency

• η = Input Load (E₀)/ Output Load(E₁)

We know from simple physics that the energy of a body is directly proportional to its mass. Here, in the working of a motor, mass may not be involved directly, but the electrical energy required to provide a function will likely have more efficiency when working with lesser masses.
